Sydney Olympic Park is one of a number of places along the Parramatta River that contains saltmarsh meadows and mangrove forests – these valuable ecosystems are natural breeding habitats for saltwater mosquitoes (Aedes vigilax). Saltwater mosquitoes are active during the warmer months, and their population peaks during summer and early autumn, following rainfall and unusually high tides.
What are we doing to manage mosquitos
Sydney Olympic Park Authority in collaboration with scientists from NSW Health Pathology implements an ecologically sustainable mosquito management program. This program delivers an annual monitoring and advisory service that guides a mosquito management program aimed to reduce pest mosquitoes on lands under our care to improve comfort levels for people living, visiting and working in the area.
The program involves:
Bti is designed to kill mosquito larvae without harming people, pets or the general environment. It targets the gut wall of larvae, killing them before they become adults. Post-treatment monitoring by Sydney University’s Department of Medical Entomology has shown that larval mosquito populations are generally reduced by 90% or more.
Mosquito breeding times and treatment days are highly dependent on tides, rainfall and temperature. Bti needs to be applied at a specific stage of the mosquito lifecycle to be effective, so treatment windows are very short. Between four to eight treatments are generally applied per season.
